Storage Redundancy (1 / 16): A company is using Azure Storage services for their data. They are currently using GRS for their data storage and replication. The company is planning a strategy to enhance disaster recovery capabilities and is considering moving to GZRS. What would be the main advantage for the company to switch from GRS to GZRS?
Answer:
The data would be copied across three Azure availability zones in the primary region, improving disaster resilience.
Explanation: Both GRS and GZRS provide high durability, and both perform synchronous and asynchronous replication. However, GZRS improves resilience by copying data across three Azure availability zones in the primary region, which is beneficial for disaster recovery.
Both GRS and GZRS replicate data asynchronously to a secondary region after a write operation, so this does not provide a unique advantage for GZRS.
Both GRS and GZRS copy data synchronously three times within the primary region, so this characteristic doesn't differentiate GZRS as a better choice for enhancing disaster resilience.
Both GRS and GZRS provide high durability of 99.99999999999999% (16 9's) over a given year. Therefore, switching to GZRS wouldn't increase this durability.
